An efficient protocol of somatic embryogenesis (SE) has been developed for the first time in four half-high blueberry (Vaccinium corymbosumL. × V. angustifoliumAit.) cultivars. Thidiazuron (TDZ), a plant growth regulator with potential activities for shoot regeneration and shoot proliferation, was found most effective for somatic embryo formation when added to a nutrient medium at high concentration (9 µM). Although TDZ was also best for embryo germination at low concentration (2.3 µM), it was followed by zeatin at 4.6 µM for the same. Plantlets developed from SE were removed from the nutrient medium and transferred on a peat: perlite medium where 100% survival rate was acquired following the acclimatization process in a greenhouse. The concentrations of total phenolic and flavonoid contents were higher in greenhouse-grown conventionally cutting-propagated donor mother plants than those of respective SE plants for ‘St. Cloud’, ‘Patriot’ and ‘Northblue’ but not for ‘Chippewa’. The effect of propagation method and/or the older age of donor mother plants were clearly visible exclusively as the 15-year-old donor plants showed higher level of 2,2-diphenyl-1-picrylhydrazyl scavenging activity than the eight-weeks-old SE plants in all four cultivars.

The berry crops in genus Vacciniun L. are the richest sources of antioxidant metabolites which have high potential to reduce the incidence of several degenerative diseases. In vitro propagation or micropropagation has been attractive to researchers for its incredible potential for mass production of a selected genotype in a short time, all year round. Propagation techniques affect the antioxidant activity in fruits and leaves. Total antioxidant activity was higher in the fruit of in vitro propagated plants compare to the plants grown ex vivo. This review provides critical information for better understanding the micropropagation and conventional propagation methods, and their effects on antioxidant properties and morphological differentiation in Vaccinium species, and fills an existing gap in the literature.

Shoots of three lingonberry (Vaccinium vitis-idaea L.) cultivars, ‘Regal’, ‘Splendor’, and ‘Erntedank’ and two clones from natural stands in Newfoundland were initiated in vitro from shoot tip and nodal explants on modified Murashige and Skoog (MS) medium containing the plant growth regulators N6-[2-isopentenyl]adenine (2iP) (12.3 μM) or zeatin (5.7 μM). Zeatin was more effective than 2iP, and induced proliferation of 2 to 3 times as many shoots in ‘Regal’ as 2iP. Out of four media tested for shoot proliferation, modified MS medium was found more effective than the Woody Plant Medium for shoot multiplication. With all three cultivars, a reasonable balance in terms of shoot multiplication rate and desirable growth characteristics was attained in a new medium. Nodal explants of the two clones cultured on the modified MS medium with 12.3 μM 2iP produced 4 to 6 healthy axillary shoots per explant in clone 1 and 2 to 4 shoots in clone 2. Shoots rooted well ex vitro directly on a 2 peat: 1 perlite (v/v...
